Do faulty ignition coils in Changan Karvaan lead to low fuel efficiency and increased emissions in Pakistan’s urban traffic conditions?

Incomplete combustion from coil failure can burn more fuel. Are drivers noticing poor mileage and unusual exhaust fumes?

Yes:

Faulty coils cause incomplete combustion, leading to:

Poor fuel mileage.

Black o r white smoke from the exhaust.

Rough engine performance.

Urban traffic makes the issue worse due to frequent stop-start cycles.

⛔ Conclusion: Coil failure directly affects combustion efficiency, resulting in higher fuel consumption and pollution.
